BRICE SMITH: Hi, this is Brice Smith from the SAS
accessibility team.
Here at SAS, we've created innovative technology,
so people with visual impairments and blindness
can independently explore network diagrams.
In this video, I'd like to show it to you.
First, we'll take a look at some of these features.
And then we'll demonstrate an example
as we investigate insurance fraud using Visual Investigator
10.8.
I'm using the JAWS screen reader.
I have Visual Investigator 10.8 open in Chrome,
and I've turned down the setting to enable non-visual access
to data visualizations.
This setting is persistent, which
means I won't need to turn it on again.
From the alerts page, I've opened an alert
and then navigated to the network diagram for it.
Visually, there's a blue dot at the center
of the diagram on screen.
It represents my virtual location diagram.
I can move this virtual location using the arrow keys,
and as I press the arrow keys, JAWS
tells me where I'm located in the diagram and the number
of objects around.
JAWS: 291 units north.
Showing 37 of 37 objects.
291 units east.
Showing 37 of 37 objects.
BRICE SMITH: I can press zero to reset my virtual location back
to the center of the diagram.
JAWS: Zero.
Moving to center.
Showing 37 of 37 objects.
BRICE SMITH: People who are visually impaired or blind
often use a cane to navigate safely and effectively
in their community.
They do this by reaching out with the cane
to find and explore objects in their environment.
From my current location, this diagram,
I can reach out and sweep what we
call a virtual cane around this diagram
to explore nodes and links.
I do this by pressing the Page Up and Page Down keys.
When my virtual cane finds an object,
JAWS tells me the name of the object, its distance from me,
and the direction to the object.
JAWS: Page Down.

BRICE SMITH: As I find objects with the cane,
pay special attention to the sounds they make.
The nodes and links make different sounds depending on
whether they're in front, behind,
or to the left or right of me, as well as how far away from me
they are.
You can also hear the difference between a node and a link.
A node makes one sound and a link
makes two sounds, which represents the two
notes it's connected to.
JAWS: Page Up.

BRICE SMITH: That's a node with one tune.
JAWS: Page Down.
Link accounts.
Document link to adjacent.
474 units at 1:00.
BRICE SMITH: And that's a link with two tones.
When my virtual cane is touching an object,
I can move my virtual location to it by pressing Enter.
JAWS: Enter.
Moving to link accounts.
Document link.
Two adjacent.
Showing 37 of 37 objects.
BRICE SMITH: If I want to know more information
about where I'm at and what's around me,
I can press the Slash key.
We call this the Where am I Command.
JAWS: Slash.
Your coordinates are 661.257 28.81 you are at link accounts.
Document link.
Two adjacent.
Showing 37 of 37 objects.
BRICE SMITH: When I pressed Slash,
you may have noticed there were 37 objects in this diagram.
I can filter the diagram by pressing the F key
to show me things like all objects,
all nodes, or even just adjacent objects or adjacent nodes that
connect to the object I'm located on.
JAWS: F. All nodes 19.
F. Adjacent objects two.
BRICE SMITH: All these features enable
me to get a better sense of what's around me
in this network.
All right, so now I'm going to use
JAWS to investigate this network diagram
and to find any suspicious connections between entities.
First I'll reset the diagram by pressing zero,
and then I'll filter it to only show me nodes.
JAWS: Zero.
Moving to center.
Showing 37 of 37 objects.
F. All nodes 19.
BRICE SMITH: I'm going to go ahead and sweep my virtual cane
counterclockwise a few times with the Page Up key.
JAWS: Page Up.

BRICE SMITH: So here, my virtual cane
has found a node to the doctor's office.
Let's go ahead and explore this node a bit more.
I'll jump to it with the Enter key.
JAWS: Enter.
Moving to Dr. EFG.

BRICE SMITH: I'm going to set my filter to adjacent objects,
so that when I sweep the cane I only find objects connected
to this doctor node.

BRICE SMITH: So when I used the cane,
I noticed there was a couple links connected to this node.
One of them is a link to an account that seems interesting,
so I'll move my location to it.
JAWS: Enter.
Moving to link accounts.

BRICE SMITH: Now that I've found the link for the account,
I'll sweep my cane to find the account and then move to it.

Showing 37 of 37 objects.
BRICE SMITH: From here, I'm going to switch my filter
to only show me adjacent nodes.
This will allow me to find nodes that are connected back
to this account number.
JAWS: F. Adjacent nodes two.
BRICE SMITH: And I'll sweep the cane to find nodes.

You are at 29104408576.
Business account.
Two adjacent.
BRICE SMITH: I heard there are two adjacent nodes,
and I've learned that this account
number is used for the doctor's office and the pharmacy.
This seems suspicious to me, so next I'll
reach out to the Secretary of State
to make sure there's common ownership of the doctor's
clinic and the pharmacy location.
And if there is, I'll group them together
to make my network easier to understand.
This was a quick demo for how to explore a network
diagram, the screen reader using Visual Investigator 10.8.
We hope it was helpful.
